The **½” UNF Plug** (part number 11234) is a threaded component used to seal one of the ports (unused inlets or outlets) on the **CAV 296** type fuel filter head (or Lucas 296 type). Its primary specification is the **imperial thread pitch (UNF)**, indicating compatibility with filter heads that use this standard of fittings.

Application
CAV 296 fuel filter heads may have more threaded holes than necessary for a specific application (e.g., for mounting flexibility or for adding sensors). This plug ensures the airtight sealing of any unused port with a ½” UNF thread, preventing fuel leaks or air ingress into the system.
IMPORTANT: This plug is only compatible with filter heads that have **UNF** (imperial) thread fittings. It is not interchangeable with metric plugs. An appropriate sealing washer (not included in this description, but necessary for a watertight seal) should be used.
